A Study on the Location System Based on Zigbee for Mobile Robot

Abstract

As a wireless communication technology, Zigbee has been used in the mobile robot’s location in recent years. An experimental system composed by a Zigbee network, a PC and a robot is designed to study the location accuracy of Zigbee location technology. The hardware and software platform are constructed. The influence of the layout and the number of reference nodes on the location accuracy is discussed. The results show that ZigBee-based robot position method can meet the requirements of mobile robot applications. The location accuracy in the layout of triangle is up to 0.636m (in the range of 4m4m) and is better than those in the layouts of rectangle and cycle .
